Issues with base_deps archive for apple_all_static config

[veloman-yunkan]

Base deps archive for the apple_all_static config contains more stuff than is eligible for being qualified as base dependencies. I looked into versions 23 and 24 of the base deps archives, but it seems to be an old problem.

Stuff that, IMHO, shouldn't be there:

• libzim stuff (libzim.a, zim header files) in the INSTALL directory of the build trees of al subconfigs^†
• libkiwix stuff (libkiwix.a, kiwix header files) in the INSTALL directory of the build trees of al subconfigs^†
• merged.a in the INSTALL directory of the build trees of al subconfigs^†
• entire xcframework tree under BUILD_apple_all_static/INSTALL/lib/CoreKiwix.xcframework/

---

^† the build trees containing build artifacts of concern are

• BUILD_arm64-apple-macos
• BUILD_x86_64-apple-darwin
• BUILD_aarch64-apple-ios
• BUILD_x86-apple-ios-simulator
• BUILD_aarch64-apple-ios-simulator

This was discovered during the work on #951 and seems to be at least partly responsible for the weird findings made while inspecting the intermediary results.
